Apple TVs are small devices allow you to stream content directly to your TV. They must be connected to both your TV and the network in order to function. Because of the security used on Tigernet2, they cannot connect wirelessly. You will need to plug the device into the ethernet jack using an ethernet cable.
Once you have your Apple TV properly connected, we will need its MAC address to register it. To locate the MAC address of your Apple TV, choose Settings > General > About. Once you have the MAC address, you can send it to us at the Help Desk, and we will register it for you.
If you have any other issues with your Apple TV, Apple has set up an excellent support page which can be found here: Apple TV Support Page.
